18*5e3eaea3SApple OSS Distributions<h3>DESCRIPTION</h3>
19*5e3eaea3SApple OSS Distributions<p>
20*5e3eaea3SApple OSS DistributionsThe <strong>thread_assign_default</strong> function assigns <var>thread</var> to
21*5e3eaea3SApple OSS Distributionsthe default processor set.
22*5e3eaea3SApple OSS DistributionsAfter the assignment is completed, the thread executes only on processors that
23*5e3eaea3SApple OSS Distributionsare assigned to that processor set.  Any previous assignment of the thread is
24*5e3eaea3SApple OSS Distributionsnullified.
25*5e3eaea3SApple OSS Distributions<h3>NOTES</h3>
26*5e3eaea3SApple OSS Distributions<p>
27*5e3eaea3SApple OSS DistributionsThis variant of <strong>thread_assign</strong> exists because the control
28*5e3eaea3SApple OSS Distributionsport for the default
29*5e3eaea3SApple OSS Distributionsprocessor set is privileged, and therefore not available to most tasks.
30*5e3eaea3SApple OSS Distributions<h3>RETURN VALUES</h3>
31*5e3eaea3SApple OSS Distributions<p>
32*5e3eaea3SApple OSS DistributionsOnly generic errors apply.
